Leo Ulloa scored the first ever hat-trick at The Amex to keep Albion firmly in the play-off places.

The Argentinian striker opened his league account at his new home ground with two classic headers and a cool finish of a one-on-one as the Seagulls beat Huddersfield 4-1.

David rounded things off with a penalty.

Albion were level at 1-1 for most of the second half, thanks to James Vaughan’s brilliant overhead kick equaliser for Town in the 42nd minute.

Peter Clarke twice cleared off the line from David after the break.

But David’s corner was headed home by Ulloa on 76 minutes to make it 2-1 as the floodgates opened.

Ulloa charged through to round keeper Alex Smithies and add his third two minutes later.

David struck from the spot on 81 minutes after sub Craig Mackail-Smith was fouled.

Ulloa departed soon after to a standing ovation.

His opener, on 20 minutes, was a powerful near-post header from Andrea Orlandi’s cross.
